A plurality of mounting grooves are arranged on the outer periphery of a plurality of rotor plates fixed to a horizontal shaft in the longitudinal direction of the shaft and provided at equal intervals, and a striking plate having a mountain-shaped (trapezoidal) concave groove extending in the longitudinal direction on both sides. In order to mount in each row of mounting grooves, an inclined surface is formed on both sides of each mounting groove so as to incline so that the shaft side expands, and the gap between the outermost rotor plates is formed on both sides of each row of mounting grooves. A holder having a suitably larger length and having a ridge that can be engaged with the concave groove of the striking plate so as to be movable in a required range in a radial direction of the rotor plate along the inclined surface. Is known.
-48983). In this rotor, the striking plate is pushed from the side between the holders, and the striking plate and both holders move radially outward due to centrifugal force due to the rotation, and the striking plate is firmly held by the wedge action of the inclined surface and the holder. Is what is done. In addition, a plurality of mounting grooves are arranged on the outer periphery of a plurality of rotor plates fixed to a horizontal shaft at equal intervals in the longitudinal direction of the shaft, and have a mountain-shaped (trapezoidal) convex strip extending in the longitudinal direction on both sides. In order to mount the plates in the mounting grooves of each row, there is also known a structure in which a clamping piece having a concave groove capable of engaging with the ridge of the striking plate is mounted on both sides of each mounting groove (Japanese Patent Publication No. Hei 2- No. 46262, Jitsuhei 2-24
No. 31). In this rotor as well, the striking plate is pushed from the side between the clamping pieces, and the rotation causes the striking plate to move radially outward due to centrifugal force, and the striking plate is firmly strengthened by the wedge action of the mountain-shaped ridges and grooves. It is something that is pinched.

撃式破砕機のロータを提供することを目的とする。However, in the rotor of the conventional impact crusher, the impact plate is attached to and detached from the rotor by pushing and pulling the impact plate laterally (in a horizontal direction parallel to the shaft). On the other hand, the weight of the impact plate is large, and if a highly sticky material such as asphalt waste material adheres to the impact plate, it becomes very difficult to pull out the impact plate. There is a problem that requires a replacement device.
Therefore, an object of the present invention is to provide a rotor of an impact-type crusher that can easily replace an impact plate with only a normal lifting machine such as a chain block.
